End buyer/investor ROI and net profit analysis

[Krishonda Johnson]

I've seen on most websites that wholesalers keep it simple when advertising to end buyers/investor. For example 

ARV 100,000

SELLERS PRICE 20,000

REHAB/RENO 1,000

PROFIT 79,000

but does the end buyer/investor want a complete breakdown of his expenses (closing, holding, etc.) Subtracted from the profit to show a more accurate profit? 

Im currently trying to come up with a ROI for the end buyer but i get to deep into how much he will spend but in reality im not exactly sure how much he or she will have to spend but sure they know. So is that something they factor into the profit?
